--- Comment #14 from Tobias Jakobi liquid.acid@gmx.net 2007-10-24 17:38:27 --- I have a savegames with an area where the 'effect' is much more noticeable, meaning a lot pixels with 'wrong' color are rendered at polygon edges. I can provide a screenshot tomorrow, but I must say it's not going to be any brighter. The area is in the subway station on the rails, naturally a quite dark setting.
The whole game is very dark, so I'm going to have a hard time finding an area with lots of light and the same effect (the rail tracks seem to be constructed in such a way that triggers the 'effect').
